Patent GB-2066925-A (GB)
Title: Universal joint lubrication
IPC: F16D3/41
Filed: 1980-11-19
Abstract: Improved lubrication of bearing cups in universal joints is provided. A universal joint has a cross, which includes a central portion and trunions extending outwardly therefrom. Each of the trunions has a substantially cylindrical cavity which is open at its outer end. The cross has passages extending from the central portion which communicates with each of the cavities. The passages and the cavities contain a grease like lubricant to provide for lubrication of the bearing cups. A lubricant agitator is located in each of the cavities. The agitator is composed of an element 24 which is denser than the lubricant and is capable of moving around the inside of the cavity. The agitator keeps the lubricant homogeneous while the cross rotates. <IMAGE>

Title: A sensor for a physical value
IPC: G01P3/42
Filed: 1981-01-30
Abstract: A sensor 10 is proposed for a physical value (for example speed, path, angular position, pressure) wherein the sensor output value is influenced by a second physical value (for example temperature, pressure). This influence is used to sense the said second physical value whereby two physical values can be sensed by a single sensor. This influence results in a variation in a sensor parameter (for example internal resistance, supply current). This is sensed in bridge circuit 12, 13, 14 and is converted into a value which is in accordance with the second physical value. <IMAGE>

Title: Paper machine having a head box with a plurality of tuyeres
Inventor: EGELHOF DIETER
IPC: D21F9/00
Filed: 1982-03-31
Abstract: The head box with tuyeres (100) has a tuyere chamber (120), two converging outer walls (95, 96) and an outlet nozzle (121) of the tuyere. There is provided at least three separate supply systems for the chamber with different liquids and those systems are arranged so that the three liquid streams, having the width of the machine, traverse the chamber of the tuyere. The two streams flowing on the outer walls (95, 96) consist of fiber suspensions, with which a two layer fiber band is formed, for example in a two web molder (101-106). The central stream has no fresh fibers and water is preferably used and such water is therefor used to separate the two suspension fiber streams. Thus it is only the matter of arranging in the chamber of the tuyere (120) narrow walls (124), at the most in the inlet area. With the water stream forming the separation layer, it is also possible to bring filling material and fine material to the fiber bands, in the course of formation.

Title: Missiles
Inventor: BARTLETT RONALD PETER
IPC: F42B15/01
Filed: 1982-10-05
Abstract: A missile (10) having a longitudinal axis (11) parallel to a design direction of flight has a window (16) of radiation transmissive material aligned at an angle to the longitudinal axis, through which radiation emitting and/or receiving apparatus (17) eg. a passive infrared, semi-active laser or television device, may emit or receive radiation. When the missile is in flight, jet producing means, which may be in the form of a forward facing intake (19), air passage (20) and slit nozzle (21), produce a jet of fluid forwardly of the window (16) so that the airflow is caused to separate from the missile body upstream of the window and is prevented from reattaching in front of or on the window, so as to limit the aerodynamic heating of the window.

Patent GB-2139114-A (GB)
Title: Co-spray abrasive coating
Inventor: EATON HARRY EDWIN
IPC: F01D11/12
Filed: 1983-05-06
Abstract: An abrasive grit is coated on a substrate by generating a high temperature plasma stream, injecting particles of matrix material into the stream, injecting downstream of the matrix material particles of abrasive grit and at such a distance from the substrate that the matrix particles and the grit particles come into simultaneous contact with the substrate surface and traversing the plasma spray gun across the substrate to be coated. The grit particles may be injected near to the substrate so that angularity of the grit particles is preserved by only limited contact with the plasma stream. A narrow substrate may be offset from the axis of the plasma spray stream to avoid the erosive zone at the axis of the spray. The coating of gas turbine blades is referred to.

Title: Web feed tangential to blanket cylinders in offset printer
Inventor: WECH ERICH
IPC: B41F7/12
Filed: 1983-10-12
Abstract: Several printing units (1 to 4) each having two blanket cylinders (6,7; 10,11; 14,15; 18,19) between which the web (5) is conveyed for first and second printing are arranged one behind the other in the web travel direction. To improve the printing quality, the web (5) is introduced at approximately right angles ( alpha ) with respect to a plane (B) containing the axes of the blanket cylinders (10,11) into the second and subsequent printing units. This means that the web (5) reaches the printing zone without wrapping around either of the blanket cylinders (10,11). The partial wrapping around a blanket cylinder (e.g. 10), which is desirable per se, does not occur until behind the printing zone, but this no longer has a disadvantageous effect on the printing quality. The tangential entry and partially wrapped around exit can be achieved by inclining the said planes (A,B,C and D) to each other for adjacent units and/or staggering the cylinders of adjacent units in the vertical direction. <IMAGE>
Patent GB-2132348-A (GB)
Title: Method and apparatus for determining the presence of oxygen
Inventor: BACON JOHN ROGER
IPC: G01N21/76
Filed: 1983-12-20
Abstract: An oxygen sensor (10) has an inorganic complex, usually a complex of platinum group metals, with  alpha - diimine ligands immobilized in a polymer support. The metal complex is a luminescent material quenchable by oxygen. The polymer is permeable to oxygen and impermeable to interfering quenchers. Oxygen concentration in a gaseous or liquid environment is determined by exposing the sensor to the environment and measuring the quenching-related decrease in intensity or lifetime of luminescence. In one version, a reference device (12) has areas of differing depth or concentration of luminescent material immobilized in a support which is relatively impermeable to oxygen. Matching the luminescence of the sensor (10) with the luminescence of an area of the reference device (12) determines the extent of quenching and the concentration of oxygen. An alternative sensor has a mixture of luminescent materials having differing sensitivities to oxygen quenching and differing colours of emission. <IMAGE>
